Abstract

We study linear and nonlinear optical properties of <I>d</I>-electron Kondo system. The effect of Kondo resonance in optical conductivity is to creat a remarkable peak inside the gap. In third harmonic generation spectra also there appear structures inside the gap which correspond to three and two-photon processes from lower Hubbard band to the Kondo resonance state. Behavior of two and four-current correlations near to ν≈0 in Kondo regime can be understood by an asymptotic analysis which reveals a marked difference between two and four-current correlations.
